Problem
A crate on a warehouse floor experiences the following horizontal forces: Worker P pushes it toward the north with 40N, Worker Q pushes it in the same direction with 25N, kinetic friction opposes the motion with 50N toward the south, and a gentle breeze also exerts 10N toward the south. (i) Determine the magnitude and direction of the net horizontal force on the crate. (ii) Will the crate remain at rest or start moving? Give a brief reason.
